ROUND-TOP EXTENSION-TABLE.

To all whom it may concern:

Be it known that I, CHARLES W. MUNZ, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented certain new and useful Improvements in Round-TopExtension-Tables, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention relates to round-top extension tables and consists in thepeculiar construction of the extension leaves and the means forsupporting and storing the same.

In the drawings, Figure 1 is a perspective view of the table, partlyextended; Fig. 2 is a bottom plan view of a portion of the table; Fig. 3is a cross-section on line 00-.02 Fig. 2; Fig. 4 is a section on liney-y thereof; and Fig. 5 is a plan view of a modification.

A is the stationary section of the table top which is preferably roundin contour, although not necessarily of a true circular form. This topis supported upon a suitable standard A and is preferably provided nearits outer edge with a depending rail B.

The extension port-ion of the table comprises a plurality of leaves O,which, when arranged in circumferential series, will completely surroundthe stationary top and enlarge its perimeter, while maintaining the sameform. These leaves are preferably grouped in pairs, the members of whichare permanently secured to each other, so as to permit of extendingoppositely in the same plane, or of being superposed in parallel planes.As shown, the connection between the two members of each pair is formedby hinging their adjacent ends, as by the hinge members a Z)respectively upon the outer and inner edges of the leaves.

D are radially-movable extension arms, upon which the leaves aresupported in extended position. These extension arms are arranged inline with the joints between the leaves and are secured to the underside of the table top, as by guides 0, so as to be capable of outward orinward movement. The depending rail Bis slotted at d for the pasSpecification of Letters Patent.

sage of the arms D and, when these arms are moved inward, the outer endsthereof will close the apertures d and impart a finished appearance tothe table.

Inasmuch as the circumferential length of the leaves is greater than thecircumference of the stationary table top, it is obvious that theycannot be stored beneath said stationary top in a single plane. If,however, the hinge sections are folded, the contraction in length willbe such as to permit of storing the several folded pairs beneath thestationary top. To this end, suitable supports are provided beneath thestationary top with which the folded sect-ions may be engaged and, asshown, these supports are formed by clips E F. The clip E is secured tothe depending rail B and engages with the outer edge of the leaves,while the clip F is secured to the stationary table top and engages theinner edge of the leaves. Thus, by disengaging the leaves from theirsupporting arms D, they may be carried under the depending rail B andengaged with the clips E F. The inner clip F is formed of spring metal,so as to permit of moving the outer edge of the leaves sufficientlyinward to clear the end of the clip E, after which the leaves are raisedand moved by the tension of the spring outward into engagement with theclip E.

To simplify the operation of contracting or extending the table, eachpair of leaves is connected to a corresponding pair of the slides D. Asshown, these connections comprise the links G H which are suitablysecured at their inner ends to the inner ends of the extension arms D,and at their outer ends these links are hinged to each other and engagea slotted bearing I secured to the lower face of one of the leaves. Thehinge connection between the links G H permits them to change theirangularity during inward or outward adjustment to compensate for therelative movement of the arms D in their respective radial planes. Thus,whenever a pair of leaves are disengaged from the clips E F and drawnoutward beneath the rail B, they will draw along with them the arms D,until the latter are sufficiently extended beyond the edge of thepermanent table top to afford support for the extension leaves. In likemanner, the inward movement of the leaves will shove inward the arms D.The engagement between the several pairs of leaves is preferably formedby tongues e and grooves f on adjacent edges. A tongue 9 is also formedon the inner edge of the leaf and a complementary groove h is formed inthe edge of the table top to receive the said tongue.

The construction being as described, in operation supposing the leavesto be stored, the operator first disengages one pair of leaves from theclips E F and draws them outward, thereby also drawing the arms D.During this movement, the leaves pass beneath the rail B, while the armsD pass through the slots (Z in the rail, as previously described. Theleaves are then placed upon the top of the arms by first elevating oneend and then the other, and sufficient lateral movement is permitted bythe links G H to allow the leaves to pass between the extended arms. Theleaves, when drawn outward, are moved sufficiently to provide thenecessary clearance of the outer edge of the table top and, after theyhave been engaged with the arms D and unfolded to bring the two membersof the pair in the same plane, they may be moved inward until the tongue9 engages the groove E. This is accomplished without imparting anymovement to the arms 1) by reason of the lost motion of the links G H inthe slotted bearing 1.

All of the pairs of leaves are successively manipulated in the mannerjust described and when the last pair is moved inward into engagementwith the table top, the interlocking tongues and grooves e f will secureall the members of the series to each other. In the reverse operation ofcontracting the table and storing the leaves, the sections aresuccessively drawn outward to dis engage the tongues and grooves, arethen folded and then lowered beneath the arms D and moved inward untilin position for engagement with the clips E F.

In place of a tongue and groove engagement between the leaves and thestationary table top, a dowel and socket engagement may be used, asillustrated in Fig. 5.
